I have a question about my model and texturing

Hello! I am nearly completely new to substance painter and I have a question about something occuring on the sort of outer texture of my model I am hoping to texture. These images are before and after baking my mesh map, and I am wondering why the model looks this way and it is affecting how textures look on my model. How can I fix it so that the textures go smoothly on and do not look like random segments are sewed together? Thank you!
